Be Iit known that we, ELME'R J. Grass and DAVID. XV, THUnsToN, both citizens of lthe United States, residing at Pittsburgh,

legheny County, ,Pennsylvania have in` vented a new and useful Improvement in Unloading Devices, of which the following is afull, clear, and exact description, reference being had to the accompanying drawings, forming part of thisspeciiication.

This invention relates to an improvement in unloading-'devices and is more particularly designed for unloadingcars containing material to be wasted, or fill material such slag .or cinders for grading railroads, etc. `The object oiiou'r invention is to provide an eflicient device ot this lcharacter which is arranged to be moved over the tracks of a railroad and which is provided with rails mounted thereon arranged to be connectedwith the railroad tracks, the arrangement being such that the cars of lill material ,can be moved from the railroad to` the trackon the unloading device. The unloading device is provided with lone or more hoppers for ren ceivingthe material from the cars, and is also provided with a conveyor vfor conveying. the material from the unloading device transversely with relation to the tracks to a suitable distance therefrom.

The precise nature of our invention will be best understood by reference tothe aecompanying drawings which will now be described, it vbeing premised, however, that various Ychanges may be made in the details of construction and the general arrangement of the parts without departing from the spirit and scope of our invention asdefined in the appended claims.

Figure l of the drawings is a side elevation of a portion of our improved unloading or till handling machine. p

Figure la isa similar view of the other portion thereof. y

Figure 2 is a plan view. y

Figure 3 is an end view ypartially in secv tion with the ramp or inclined track re moved. y,

Figure 4 is a plan view of a till-receiving hopper. y

Figure 5 is a longitudinal section .through the hopper shown in Figure ,and in which we have shown a plurality ,of adjustable baiiie plates, and o F'gure is an end view of a modified form of machine. f

Referring to Figures l to t rofthe drawings, the reference character 2 designates trucks at each end of the machine having longitudinal sills 3; and d car wheels mounted on suitable axles, which are journaled in suitable bearingsy whichare connected to the longitudinal sills 3. Connected lto the longitudinal sills 3 of the trucks 2,;by means such as a pin and slot @permitting relative inovement, are intermediate Alongitudinal sills 5, which are on a llower plane than the sills 3 and mounted on the sills 3 and 5 are cross ties 6. The cross ties on the sills 5 are in a lower plane than they ties'on the sills 3, and supported on the cross ties on the sills 5 are stringere? which, together with the cross ties on the sills 3, are arranged to sup4- por't longitudinally extending railsl 8.

These rails `8 extend froml rend toend of the structure. and are connectedto thefraills `9 'of aV railroad track'on which the wheels 4 of the device are mounted, by means of lrails 10, supported on inclined stringers 11.

The ends of these stringers l1 adjacent to the unloading machine are supported `on transverse Lbeams l2 on the trucks.

Supportedl on the frame work of the: unloading machine are transversely arranged hoppers y12 closed at one end, as indicated .at 13 in Figure 4. These hoppers are provided with openings 14? for the reception ofthe stringers 7. Extending transversely from thev unloading machine are boom members 14, which are connected to the framework of the unloading machine and are also supported by means of guy rodsl, arranged -to support the outer ends thereof. lThese boom members are also connected to, each other by means of vertical struts 16 and angular bracemembers V17."

' In the drawings we vhave shown two hoppers and two boom structures in connection with the unloading machine, which are so spaced with relation to each other that the hoppers will be positioned under ,they two drop gates of `coal oars of the usual pattern, or cars of a similar type. We desire yit to be understood, however, that thenstructure may be of suiiicient length and be provided Ywith suliicienthoppers to unload a plurality of cars simultaneously.

Mounted in pairs on the boom members 14 are a series of rollers18, which are arranged to' support'an endless carrier 19, which passes over a driving pulley 20 at the outer end of the boom structure, and a pulley 21 at the other end thereof. The pulley 21 is mounted on a shaft which is journaled in adjustable bearings and which are adapted to be adjusted by means of the take-up device .22, in order to take up theslack in the conveyor. Secured to the shaft on each of the pulleys 2O is a driving pulley 23, which is connected by means of a belt 24C witha pulley 25 on a shaft 26. The shaft 26 is connected to a driving mot-or 27 by means of a universal coupling 28, and 29 is a similar coupling in said shaft between the pulleys 25 arranged to drive the adjacent conveyors, as clearly shown in Fig ure 2.

Connected to the boom members 14 and on each side of each of the conveyor belts are metallic strips 30which form guides for the material moved along on the conveyors 19. These strips are made up of sections, a number of which are arranged to be swung at an angle to the conveyor yas indicated in chain lines at 31, in order to scrape the material from the conveyor before it reaches the end of the boom structure.

Extending longitudinally of the unloading device and transversely with relation to y the hoppers and within each of the hoppers,

as clearly shown in Figure' 3, are a plurality 'of baflie plates 32, which are arranged to support aportion of the load of the material dumped from the cars to prevent over loading the conveyor.V These baffle plates may be formed integral with the structure, as shown in Figure 3 of the drawings, or may be arranged to beadjusted to different inclinations by the lever mechanism shown at 33 in Figure 5 of the drawings. Cars such asl shown at 35 in Figuresl and 3 of the drawings are run onto the rails 8 of the device, as indicated in the drawings, and the drop gates are then opened to permit the material to fall from the car into the hoppers, which material is transferred from the hoppers outboard by means of the endless conveyors which are continuously driven by means of a motor 27.v If all of the members such as shown at 31, are parallel with the endless conveyor, the material will be conveyed to the end of the boom structure from which it will fall by gravity, but if any of the sections 31 are placed at an angular position the material will4 be scraped from the conveyors.

By providingbaffles such as 32, the danger of clogging the machine by overloading the conveyors, is avoided if the drop gates over the hoppers should be suddenly opened to from the car.

In Figure 6 of the drawings we have permit a large quantity of material to fall shown a structure similar to that shown in the otherfigures and in which we have used the same reference characters with the letter a aiiixed for designating similar parts. ln this construction we have shown an upwardly yextending frame work 36 on each side of the structure, which frame work is connected by transverse beams 37 above the line ofthe top of the cars. The boom structures in this case are formed of two members which are hinged to each other at 33 and instead of supporting the beam structures by means of guy rods, they are supported by means of a cable or cables 39, which pass over sheaves 40 to a winding drum 4:1. By meansof the winding drum and the supporting cables we are able to raise and lower the outer end ot the boom members,vtogether with the one end of the conveyor in order to enable us to increase the height of the fill, if desired, and also to lower the boom structure when first starting the fill, which will reduce the work required for driving the conveyors. By means of this structure, we are also enabled to raise the boom structure into a vertical position so that the same will be out of the road when moving the structure, and which will also permit the structure to pass obstructions along the track. f The transverse timbers 37 also form a platform yon which the workmen can stand for manipulating the bars o r rods ywhen loosening the material in the car being dumped.

It will be readily understood by those familiar with the art that the motor 27 may be provided with suitable connections for actuating the drum 41 and it may also be connected so` as to actuate a drum or wind lass for moving the cars from the main rails 9 to the rails Son the structure, as well as for moving the machine along the track.

The inclined tracks are supported on the ends of the unloading device and the railroad track, but these inclined tracks can readily be removed andl placed on the device or on suitable cars when moving` the structure from place to place.

The advantages of our invention result from the provision of an unloading device.

supported on the rails of a railroad track, and which is also provided with a track thereon, together with an inclined track connecting the track on the unloading device with the main track so that the cars to be` unloaded can be moved from the main track i up the inclined track onto the track on the unloading device. Furthermore, from the provision of a conveyor mechanism for conveying the material from suitable receptacles on the unloading device outboard from the unloading device.
